tarum’ four species are enumerated. Koch reduces the number to 
two, which he thus designates and defines :— 
“ §. acutifolia (Willd. Sp. iv. p. 688.) —Aments sessile, minutely 
bracteated, capsules ovate-conic glabrous sessile, gland protruding 
beyond the base of the ovary, styles elongate, stigmas linear-oblong, 
leaves linear-lanceolate elongate-acuminate, like the young branches 
glabrous, stipules lanceolate-acuminate. River-banks. March. S. 
violacea, Smith in Rees’ Cyclop. p. 38 (not Willd.) Bark of the 
branches dark red, covered with a dense and cesious bloom.”—Koch, 
Synop. Fl. Germ. p. 645. 
“ §. daphnoides (Vill. Dauph. iii. 765.) — Aments sessile, minutely 
bracteated, capsules ovate-conic glabrous sessile, gland protruding 
‘beyond the base of the ovary, styles elongate, stigmas oblong, leaves 
oblong-lanceolate acuminate glanduloso-serrate glabrous, when young 
villose like the young branches, stipules semicordate. In subalpine 
valleys descending into the plains with the rivers and in the marshes 
of Northern Germany. March, April. It varies with the branches 
covered with cesious bloom and destitute of it; with the young 
branches subglabrous and very hairy ; with the female catkins densely 
villose, the hairs equalling the stigmas, and less villose with shorter 
hairs ; and with the leaves broader or narrower. S. precox, Hoppe 
in Sturm. D. fl.1. 25. Willd. Sp. Pl. iv. p. 670, is the ordinary form 
with glabrous branches. S. cinerea, Willd. Sp. Pl. 460, after Link. 
H. Berol. ii. p. 414, is the variety with hairy branches. S. pomera- 
nica, Willd. Suppl. p. 60, is a variety with narrower leaves and thin- 
ner aments.”—Koch, Synop. Fl. Germ. p. 646. 
Fries, in his latest work (Sum. Veg. Scand. vol. i. p. 56), marks 
these two species as doubtfully distinct, and does not regard true 8. 
acutifolia as indigenous within his limits; but he considers that the 
Scandinavian daphnoides (Herb. Norm. vi. 51) somewhat approaches 
it in character. Ledebour (FI. Altaica, vol. iv. p. 260) mentions that 
Livonian examples of S. precox, Hoppe, have lanceolate stipules ; 
and that specimens of S. acutifolia collected on Mount Ararat agree 
with the European precox in the form of their leaves. But Koch 
(Syn. Fl. Germ. 1. c.) says of S. acutifolia :—“ It very much resembles 
the following species (S. daphnoides), yet differs in its mode of growth 
and the form of its leaves, and in my opinion it is truly distinct.” In 
this view of the case Mr. Borrer, who has studied both under cultiva- 
tion, concurs ; and he adds that S. daphnoides is a more handsome 
shrub than S. acutifolia, and flowers more freely.
